Updated default property paths

I was recently looking into how to define quorum queue creation for all bindings by default and noticed that the documentation did not accurately specify the path.

According to the current documentation:

`spring.cloud.stream.rabbit.default.quorum.enabled=true`

But it is actually:

`spring.cloud.stream.rabbit.default.consumer.quorum.enabled=true` for consumers

OR

`spring.cloud.stream.rabbit.default.producer.quorum.enabled=true` for producers.
